List, There is an IBM 3725 available in Champaign/Urbana Illinois at a local scrapper. It is large, blue, and runs on three phase (as far as I could tell). Please let me know if anyone is interested in saving it. No docs, no media, no nothing... Just a large heavy blue computer. I certainly have neither the space nor the juice to house this beast. I'm also quite interested in what it is. Thanks for your replies, and please email if you have an interest in the system. - Dan Linder / dlinder(a)uiuc.edu / upside(a)mcs.net - - Riot sounds start riots. / keep talking... -

PDP flip-chips

by lemay＠cs.umn.edu

I have a lot of M (Maroon) flip chips, with IC's on them. I have a fair number of G (Green) flip chips with transistor logic, and I have only a few of the types you mention below: R002 Diode Cluster 2 flip chips R107 Inverter 2 flip chips R111 Diode Gate 2 flip chips R602 Pulse Amp 2 flip chips B134 Diode Gate 4 flip chips B152 ? 2 flip chips B683 50 Ohm Or Bus Driver 6 flip chips -Lawrence LeMay lemay(a)cs.umn.edu > What kind of FlipChips?

New COSMAC stiff amd a VaxStation offer

by dogas＠leading.net

Wow. UPS just delivered and opening the boxes was better than sex. Newly aquired: a complete COSMAC Development System IV. Check out: http://users.leading.net/~dogas/classiccmp/cosmac/cosmac.htm Included with the pile were also about 65 original RCA documents covering Cosmac systems and options (that are listed in the above URL.) If anyone needs any related into looked up or copied... And... I've now driven approx. 500 miles and spent alot of time diging for parts to get my VaxStation 3100 running (unsuccessfully.) I have other toys screaming for my time (reference above) so I therefore propose this trade: All I want is a harddrive with VMS( and DECwindows ) and a C compiler that I can just install in my machine to plug and play. In exchange for this pre-loaded harddrive, I'll trade an internal DEC CD-ROM (and controller card for the 3100,) an internal DEC TZ30, an external RRD40 CD-ROM, and 2 VaxStation 3100's for parts. Hell, I'll through in a BA11-KE crate (minus the power supply) if you want one too.... Thanks - Mike: dogas(a)leading.net

Netscape on Solaris 2.4

by technoid＠cheta.net

I have Solaris 2.4 (or Sunos 5.4 or whatever they are calling it this week) on my Sparcstation 330. The architecture is SUN4 as opposed to Sun4m or Sun4u etc.... The openboot prom is the old style so no 'OK' message, just a wedge (>). I have installed Netscape and get the following message when I execute it. # ./netscape xlib: connection to ":0.0" refused by server xlib: Client is not authorized to connect to Server Error: Can't open display: :0.0 Other programs such as ADMINTOOL run fine. I can ping and have name services over my lan via a default router (192.168.0.3) and ftp'd Netscape onto the machine from ftp.netscape.com so I know things are working. The installation gave me a completion messages without snags. What more do I need to do? Thanks all Technoid

Altair 680 software

by charp＠bitflash.com

Hi, Does someone have a copy of the old paper tapes containing the resident editor/assembler and/or the Basic interpreter for the Altair 680? Both were bundled with the 16K memory boards. Thanks in advance, Frederic

Shugart 851 power problem

by CLASSICCMP＠trailing-edge.com

>#2 Power up the IMSAI box: >At the drives: > 5 volt line reads 1.2 > -5 volt line reads -0.9 > 24 volt line reads 2.6 >and (needless to say) the drives don't work. The Cromemco >ROM monitor gives all sorts of errors trying to access them. >... >[And other times when you power it on things are fine] >... >What gives? Does this make sense to anybody out there? It looks to me like one or more of the stepper motor phases are shorted (or their drivers are shorted) by garbage signals that come over the 50-pin Shugart interface from the IMSAI when it's powered on. Garbage signals are a fact of life, and the circuitry on the drives shouldn't respond in such an awful way to them. Two things to do: 1. Ohm out the stepper motors looking for shorted phases. 2. Check the driver transistors on the 851's. If any are hot when the problem occurs, it's almost certainly related. It's not impossible that the circuitry that drives the driver transistors is screwed up, too. It wouldn't surprise me if the foldback protection in your floppy power supply folds all the outputs back simultaneously. This certainly seems likely based on the voltages you see. If you can unhook the 24V output from the power supply (this is what runs the stepper motors) and try again, this might be useful. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Identify this LSI-11 floppy controller

by lemay＠cs.umn.edu

I have a couple floppy disk controllers from a device that contained an integrated LSI-11 cpu and a few other boards. The floppy controller is from Charles River Data Systems (C) 1978. On the connector, one of them has FC-202 / 1613 on it, the other has FC-202 / 1703. The floppy disks that were connected to it were single sided shugarts (801-2 if i recall correctly). I'm curious if these can handle DSDD, and anything else that anyone knows about it. Also, is their a web site with information on pdp-11 boards, similar to the PDP8 omnibus lists and such that are available? i'd like to be able to look up what should be common boards, such as LSI-11 cpus, 32K 18 bit MOS memory boards, various serial and parallel interface cards, etc. -Lawrence LeMay
